Introduction to relevant knowledge points of distribution cabinet base

  The base of the distribution cabinet is usually made by the installation unit on site
According to the overall dimensions of the distribution cabinet, the channel steel is sawn and welded to form, and then derusted and painted
After leveling, the base of the distribution cabinet is fixed on the ground with expansion bolts, and then the frame of the cabinet is connected with the base with bolts
Since the base surface of the distribution cabinet is provided with insulating paint, the frame of the cabinet and the base are only mechanically connected, not electrically connected
Therefore, for safety, the base of the distribution cabinet should be grounded The method is as follows: weld an M6 bolt in the channel steel base, and use 16mm2 bare steel flexible wire to connect with the grounding trunk line
If the power line goes in and out from the bottom of the cabinet, once the base of the distribution cabinet collides with the power line with damaged insulation, it will be charged, causing danger
Therefore, the base of the distribution cabinet must be grounded
Some power distribution cabinets and power supplies are all accessed from the top of the cabinet, and the bottom of the frame of the power distribution cabinet is closed In this case, the base of the distribution frame cannot contact with the power line, just as the cabinet door does not need to be grounded if it is not equipped with electrical equipment
At this time, the base of the distribution cabinet can not be grounded
The base of the distribution cabinet has the functions of reinforcement, grounding, static discharge, etc
, so general customers will also purchase the base when purchasing the distribution cabinet   Manufacturer of distribution cabinet: http://www
